Peptide Compounds
Overview

Product: Follistatin 344 (FST-344)
Category: Research Peptide
Primary Research Area: Myostatin/activin signaling
Research Focus: Skeletal-muscle growth, muscle preservation, and muscle biology

Description:
Follistatin 344 is a naturally occurring follistatin isoform investigated for its ability to interact with myostatin and activin signaling pathways. Myostatin is a negative regulator of skeletal-muscle growth, making FST-344 an important research compound for studying mechanisms involved in muscle development and muscle wasting.

Research Applications:

  • Myostatin inhibition research
  • Activin signaling research
  • Skeletal-muscle growth and development
  • Muscle preservation and wasting research
  • Muscle regeneration research
  • Neuromuscular disease research

Human studies of FST-344 have primarily investigated gene-transfer approaches in conditions such as Becker muscular dystrophy and sporadic inclusion-body myositis; these studies are early-stage and do not establish FST-344 as an approved muscle-building therapy.

Format: Lyophilized research material
Purity: [Insert your batch-specific purity]
Storage: Store according to the manufacturer’s Certificate of Analysis and handling specifications.

Research Use Only — Not for Human Consumption.

Biochemical
Characteristics

Follistatin 344 — Biochemical Characteristics

  • Peptide: Follistatin 344 (FST-344)
  • Protein family: Follistatin / activin-binding protein
  • Biological class: Secreted glycoprotein
  • Primary role: Binds and modulates members of the TGF-β superfamily, including activins and myostatin
  • Molecular relationship: FST-344 is a splice variant/precursor form associated with follistatin biology and extracellular ligand binding.
  • Research interest: Myostatin signaling, activin regulation, skeletal-muscle biology, and tissue remodeling
  • Structure: Contains multiple follistatin domains involved in ligand binding.
  • Mechanism of interest: Follistatin can sequester extracellular signaling proteins, potentially reducing their interaction with corresponding cell-surface receptors.
  • Research significance: Particularly relevant to studies examining the regulation of skeletal-muscle growth and muscle-wasting pathways.

Important: FST-344 is a research compound, and its biochemical activity should not be interpreted as an established clinical muscle-building effect.

Research Applications

Storage

Follistatin 344 — Product Storage

  • Lyophilized powder: Store frozen, typically at −20°C or below, according to the manufacturer’s specifications.
  • Protect from: Light, heat, moisture, and prolonged exposure to room temperature.
  • After reconstitution: Store under the conditions specified by the manufacturer/COA. Avoid repeated freeze-thaw cycles.
  • Handling: Minimize unnecessary agitation and temperature fluctuations.
  • Packaging: Keep the vial tightly sealed until use to minimize exposure to moisture and environmental contaminants.
  • Long-term storage: A dedicated laboratory freezer is preferred.

Important: Storage requirements can vary depending on the formulation and manufacturer. For a commercial product page, use the exact storage conditions provided on your supplier’s COA or technical data sheet rather than assuming a universal temperature.
